HENRY M. HARLEY, OF GLOUCESTER CITY, NEW JERSEY, ASSIGNOR OF ONE-HALF TOGEORGE A. HEYL, OF PHILADELPHIA, PENNSYLVANIA.

, FABRIC PRlNTING MACHINE.

SPECIFICATION forming-part of Letters Patent No. 641,104, dated January9, 1900.

Application filed June 21,1898.

To all whom it may concern: V

Be it known that LHENRY M.HARLEY, a citizen of the UnitedStates,residing at Gloucester City, in the county of Camden, State of NewJersey, have invented a new and useful Improvementin Calico or FabricPrintingMachines, which improvement is fully set forth in the followingspecification and accompanying drawings. I

My invention consists of a calico or fabric printing machine adapted toprint each side of the fabric, the same employing a set of printing andimpression rolls for printing one side of the fabric, a bridge overwhich said fabric is passed and by which it is reversed, and another setof printing and impression rolls for printing the other side of thefabric, the sets of rolls being at opposite ends of said bridge, thusproducing an accurate register in the print of the two sides or faces ofthe fabric without the employment of a large main cylinder and theengagement of printing-rolls therewith as heretofore practiced in suchmachines.

It also consists in adapting said bridge to adjust the tension of thefabric passing over the same and to produce the best results in causingthe register of the print or pattern of the two faces of the fabric.

Figure 1 represents a side elevation of a calico or fabric printingmachine embodying my invention. Fig. 2 represents a vertical section ofa detached portion thereof on an enlarged scale. Fig. 3 represents anend elevation of the machine. Fig. 4.- represents a diagramic viewthereof. Fig. 5 represents a side elevation of a portion of another formof my invention. Fig. 6 represents a top or plan View thereof. Fig. 7represents an end View thereof on an enlarged scale.

Similar letters of reference indicate corresponding parts in thefigures. I

Referring to the drawings, A designates the frame of the machine, B thehousings for the printing-roll C and impression-r011 D at one end ofsaid frame, and E the housings for the printing-roll F andimpression-roll G at the other end of said frame. The shafts of therolls are mounted in adjustable boxes for evident purposes.

Adjacent to the roll 0 is the color-feed roll Serial No. 684,039. (Nomodel.)

H, and adjacent to the roll F is t-he color-feed. roll J.

K designates the color-trough for the roll H, and L designates thecolor'trough for the roll J, said troughs being adj ustably mounted 011the frame A by means of screws M or other suitable appliances.

The rolls of each set are properly geared together, and the two setsreceive motion from the gear-wheels N, to either of which power iscommunicated.

P designates a bridge which has a slatted face and is preferably of theform of the segment of a circle and extends approximately from one setof rolls to the other, it being connected at one end with the housing Bby means of the pivotal bolts Q and supported at its other end by theuprights P, the latter being adj ustably secured at their lower ends tothe framework of th emachine. The means for adjusting said bridgecomprise slots P in the lower ends of the uprights P, that receive boltsP on the frame of the machine, said uprights being held in place by nutsupon said bolts in a familiar manner. In this way the bridge can beraised or lowered to vary the tension upon the web passing thereover. Tofurther vary and regulate the tension upon the web between the sets ofprinting and impression rollers, the delivery end of the bridge isprovided with a roller W, mounted in boxes S, that are movable inupright guides S in the sides of the bridge. The blanket passes over thebridge and around the roller W and around the impression -roller D ofthe first set of printing and "impression rollers. The boxes are engagedby the screw-threaded portion of a rotatable adjusting-rod R, supportedby a bracket T and geared, as at u, with a crank-handle V. By turningsaid handle V the roller W is raised or lowered through the intermediacyof the gearing described,as may be required to regulate the tension uponthe web between the two sets of printing and impression rollers. Thebracket T is of course suitably mounted to suit the adjustment of thebridge. The web passes from the imlivery from the impression-roll D andthe feed to the impression-roll G, whereby the web is caused to restupon said bridge at all times during its passage between the rolls, thecurvature of the bridge affording an approved bed therefor and withwhich the web is in close contact th roughout its entire length. Thecurvature of the bridge and the fact that the web approaches and leavesthe same from the convex side thereof gives the web an extended and evencontact therewith from end to end, so as to preserve the best alinementbetween the two sets of printing and impression rollers. The web movingin contact with said bridge between the sets of printing and impressionrollers and the roller V at the delivery end of said bridge beingadjustable to vary the tension upon said web it is obvious that it isheld against deviation from a direct course between said sets of rollsand maintained in the desired alinement to secure the best results incausing the patterns on opposite faces of the web to register.

I employ additional printing-rollers X X when desired and provide thesame with colorsupplying rollers Y Y and color-troughs therefor, withmeans for adjusting the same, as will be most plainly seen in Figs. 1and 2.

As usual in fabric-printing machines, I may employ the backing-sheets ZZ, which are guided on the rollers Z Z and in the present case passedaround the blanket on the bridge and rollers D and \V and that on theroller G. One backing-sheet Z leads from its roll first to and aroundthe impression-roll D, and thence across the bridge P, being situatedadjacent to the blanket passing around said ports. After passing aroundthe bridge the backing-sheet is again passed around the roll D andbridge P, this second lead being situated upon the first lead, while thepaper passes over this second lead. The other backing-sheet leads fromits roll first around the.

impression-roll G and upon the blanket thereon and is then again passedaround said roll G and upon the first lead, while the paper passes overthis second lead.

The operation is as follows: Power is imparted to the machine and thefabric passed between the rollers G and D, whereby it receives animpression, and may then pass between the rollers X and' D, where itrecives another impression, both being on the same face. Then ittraverses the bridge P and passes under the roller G, so that it may besaid to be reversed, whereby it is subjected to the printing-roller F onthe face opposite to that first printed, and may also receive anotherimpression from the roller X on said opposite face, and thus both facesof the fabric are printed, the parts of the machine being adjusted andtimed so that there is an accurate register of printing 011 the obverseand reverse faces of the fabric. The fabric after being printediscarried from the machine and directed to a drying apparatus for evidentpurposes.

When it is desired to impart motion' to the slats or face of the bridge,(see Figs. 5, 6, and 7,) said slats are connected with sprocketchainsforming an endless apron or blanket A, said chains being engaged bysprocketwheels B on the ends of said bridge, the shaft of said wheelsbeing geared with that of the adjacent impression roll 0, whereby theapron receives positive motion and so assists in carrying the fabricover the same.

Having thus described myinvention, what I claim as new, and desire tosecure by Letters Patent, is-
